Another car exhibit in a Massachusetts art museum

In an attempt to build up my skills in the Piper Arrow, an example of the “complex” airplane that must be used for an FAA flight instructor flight test, I went out to western Massachusetts on Saturday to MassMOCA, an electronic components factory converted to contemporary art museum.  The most arresting exhibit currently is by the explosion artist Cai Guo-Qiang.  He tricked out Ford Tauruses with fiber optics to simulate rockets and fireworks then hung them from the ceiling in one of MassMOCA’s largest rooms.  This is well worth the trip to the North Adams airport (KAQW; surrounded by mountains and not suitable for IFR or night operations).  If you were bored by the car exhibit at Boston’s Museum of Fine Arts you’ll like this one.

Efficient Market Hypothesis for Dating?

A friend trained in economics, let’s call her “Polly”, was over to the house for dinner last night.  She asked if we knew anyone for a twentysomething friend of hers, let’s call him “Bunbury”, who worked a demanding software management job at a big software company.  He was a “really nice guy” and she was perplexed that he couldn’t find someone.  If someone at the table had said “there is a company traded on the NYSE that is really undervalued” she would have immediately hammered him with an explanation of the Efficient Market Hypothesis:



“An ‘efficient’ market is defined as a market where there are large numbers of rational, profit-maximizers actively competing, with each trying to predict future market values of individual securities, and where important current information is almost freely available to all participants. In an efficient market, competition among the many intelligent participants leads to a situation where, at any point in time, actual prices of individual securities already reflect the effects of information based both on events that have already occurred and on events which, as of now, the market expects to take place in the future. In other words, in an efficient market at any point in time the actual price of a security will be a good estimate of its intrinsic value.”


(see http://www.princeton.edu/~ceps/workingpapers/91malkiel.pdf and http://www.investorhome.com/emh.htm).  Why then was Polly convinced that her friend was such a catch?  Applied to romance, the Efficient Market Hypothesis says that if the guy were actually worth dating one of the millions of women who live within a 30-mile radius of his house would have figured it out.


It occurred to me that all of the really nice mature easygoing people that I know are married.  If one looks carefully at a single person it is usually not hard to find an explanation for why they are not happily paired.  One might be able to find an exception in an isolated fishing community in Alaska but in a major metro area within the Lower 48 it seems improbable.


What about Bunbury?  Polly says that he is smart but presumably all of his intelligence and cleverness is expended at his 80-hour/week job, which in any case is best described as “sits at a desk and types at a computer”.  What’s left over for a potential partner is part of a paycheck.  If she wants to marry a paycheck, there are plenty of medical doctors and Wall Street guys who make a lot more than Bunbury.

B-school “hacking” incident finally fades from the news

No reporters have called in the last couple of weeks to ask about the Harvard Business School “hacking” incident, in which applicants who edited URLs could discover whether or not they’d been admitted.  I had a tough time understanding why the story had such long legs when, after all, quite a few Web sites over the past 15 years have had similar vulnerabilities.  What was unusual about the business schools is that they blamed their Web site users.  Every other publisher has secretly spanked its programmers, patched the hole, and tried to pretend that it never happened.  The B-schools, however, somehow came up with the innovative idea of blaming everything on the cut-and-pasters out there in the wider world rather than on the dazed-by-donuts coders who couldn’t get the authorizations right for various pages.  That’s what made the story different and what attracted so much press.

[This was not actually the first time that HBS had trouble with the world of commercial junkware.  They outsourced their placement office interview scheduling a few years back and the system managed to screw up students desperate for jobs in a down economy.  The student newspaper ran a cartoon lampooning the administrators responsible and the deans decided to fix the problem by threatening to expel the editor of the newspaper for violating Harvard’s speech code (see http://www.thefire.org/index.php/article/4909.html).] Full post, including comments

Samoyed versus bicycle

Life with three Samoyeds can be unexpectedly eventful.  Today I walked Alex, Roxanne (his 1-year-old cousin, staying with me for one week), and Samuel (the rescued 9-month-old from Norfolk) around Harvard Square for 1.5 hours.  On the way back to the apartment I thought it would be safe to tie them up outside a sandwich shop with Sammy near a bicycle.  When I came out with my sandwich the bike had been knocked over and he was chewing on the plastic brake lever housing.

Samoyeds in the china shop?

Eating lunch outdoors(!) in Harvard Square we ran into a facilities manager who told us about his visit to http://www.replacements.com/, a company that sells expensive china and crystal.  He said that every third cubicle was home to a dog.  Apparently the place is well-known throughout North Carolina as a dog-friendly work environment despite the fragile nature of the product.

Mobile phone with pedometer built in?

Lisa (skinny), Alex (husky), Sammy (skinny), and I (still trying to get down to 180 for flying the R22 helicopter) were walking today around Harvard Square and wondering why pedometers weren’t built into cell phones.  A Web search upon returning home revealed just one such phone and it was available only in Japan back in 2003(http://walking.about.com/b/a/036931.htm).  As our nation gets fatter and we don’t even have to get off the couch to answer the phone, wouldn’t this be a natural addition to the one electronic gadget that almost everyone carries?

Low-wage workers have to choose between car and rent

Today’s New York Times carries an article “Falling Fortunes of Wage Earners” noting that “Even though the economy added 2.2 million jobs in 2004 and produced strong growth in corporate profits, wages for the average worker fell for the year, after adjusting for inflation – the first such drop in nearly a decade.”  This is a theme in Barbara Ehrenreich’s book Nickel and Dimed, which I recently finished listening to while driving back from Virginia.  Ehrenreich did her research in the boom economy of 1998 and 1999 when labor was in short supply yet wages barely rose for the unskilled.  Ehrenreich took service jobs in Key West, Portland, Maine, and Minneapolis to see if she could make ends meet after one month.


Ehrenreich notes that the official poverty line was defined in 1964 as a multiple of the cost of food (see http://www.census.gov/hhes/income/defs/poverty.html) and has barely been revised since then.  The marketplace, however, has changed.  Real estate and rents have become much more expensive and food has stayed relatively cheap.  Thus it is easy to envision a family whose income is 3X the cost of eating at McDonald’s but who can’t afford rent.  Ehrenreich finds that almost no unskilled worker would be able to afford rent plus a car at the same time.  If they can’t team up with a spouse and they need the car to get to work they are forced to live in the car.


Ehrenreich’s conclusion is that this can’t last.  The workers will rebel and demand their right to at least an efficiency apartment plus some means of transportation to a job.  She predicts a Proletarian Revolution.  Six years have elapsed since Nickel and Dimed was written and yet the Walmartians and hotel and restaurant slaves seem as docile as ever.


What did Ehrenreich overlook?  Immigration!  There are plenty of people from poor countries who think that working 60-70 hours per week for $7.50/hour is acceptable, especially if there are opportunities for their children to do better.  As long as the immigrants are streaming into the U.S. it seems unlikely that wages for the unskilled will rise.


One might ask “Why do we have such a welcoming immigration policy?”  Countries that value quality of life restrict immigration.  To get into New Zealand, for example, you need to demonstrate some combination of youth, education, and wealth.  The New Zealanders don’t see a need to clog their neighborhoods with development and their highways with traffic unless the newcomers are bringing something interesting.  The U.S., by contrast, is happy to grant visas and green cards to people who don’t speak English and who in some cases are dedicated to the destruction of the U.S. government (the September 11th terrorists, for example, most of whom had official U.S. INS blessing).  The U.S. government puts GDP growth as its #1 priority because GDP growth enables the government to collect more in taxes and the extra tax revenue enables the government to expand.  If the population growth that is required to generate the GDP growth means that young people have to work two jobs in order to rent an apartment that’s not Uncle Sam’s problem.  High housing costs and the lack of guaranteed health care are both desired spurs to keep potential taxpayers getting up and going into work every day.


The best predictions available today show the U.S. population rising from its present 295 million to 500 million within our lifetimes.  With wages for low-skill workers set according to wages in India and China the living styles of many unskilled workers in America will have to be more like those in India and China.  Ehrenreich’s idea that a worker is entitled to an efficiency apartment does not apply in India or China.  I visited Agra, home to the Taj Majal, a few years ago.  Statistics showed that 2 million people lived there, subsantially smaller than the population of Boston and its closest suburbs, yet there were essentially no buildings taller than one story.  If a family of 8 people ran a little shop by the road they would roll down the shop door at night and sleep there as well.  A friend recently returned from living in Shanghai and reported the same system there.


We could argue about the merits of globalization and U.S. immigration policy but these factors are unlikely to change.  Better to think about how best to deal with the implications.  Low-wage workers in America won’t be able to afford housing constructed with currently prevailing methods.  In Third World countries this has traditionally resulted in shantytowns springing up (cf. Mexico City).  Perhaps with innovations in prefab housing we could provide shelter in the exurbs at a cost affordable to unskilled workers.  If not and if we have to accept the idea that a low-wage worker with a car will never be able to afford an apartment maybe the solution is an inexpensive car that is comfortable for sleeping.  If the Chinese can make a cheap car they should be able to make a cheap small RV.  If the Chinese can make a sleeping van for $10,000 (new) a low-wage worker could have transportation and minimal shelter at the same time.


Karl Marx thought that the Industrial Revolution would end scarcity, i.e., that everyone in the U.S. would be living in a McMansion and driving an S.U.V.  That was one of his main reasons for concluding that Communism would be the natural end-result of economic development.  Marx did not count on a world population explosion, however, and the simultaneous stagnation in construction technology resulting in tremendous pressure on housing costs.

Lincoln Conservation Land Off-Leash Dog Ban

One of the sad things about aging is that one’s fantasies shift from sex to real estate.  My personal suburban Boston fantasy has long been to move to Lincoln, Massachusetts and live in a house up against the conservation land where I can bike and cross-country ski with what seems to be a growing population of dogs.  People pay $2 million for the privilege of living in an environment free of Republicans, people of color (as the good liberals of Lincoln would call them), or generally anyone who can’t afford a 1-5 acre chunk of property a 20-minute drive from Harvard Square (and conveniently just five minutes from Hanscom Field where one can keep an airplane or helicopter).  One of the side benefits of being in a 100% rich community is that all of the dogs running around the conservation land are friendly to people and mostly quite playful with other dogs.  Because there is no white trash there are no white trash dogs, unlike trying to bike through the Lynn Woods, for example, where the first few hundred yards can be a gauntlet of Pit Bulls, Rottweilers, etc., all bristling for a fight with any newcomer.  The typical dog met in Lincoln, by contrast, is a tail-wagging Golden Retriever or Lab.


Paradise was lost during my trip to the South, however, and it seems that there are now signs around the Mt. Misery conservation land banning off-leash dogs.

White men bad; white dogs worse

We spent the weekend in Gettysburg, Pennsylvania with an anthropologist friend who has two 3-year-old bitches (Lab and Husky) and 4 acres of land on which Alex and Sammy could play with them.  One of the nice things about colleges located in areas where real estate is cheap is that the professors live close to the campus and are available to students for informal dinners and shared extracurricular activities.  Thus over the weekend we encountered a few other Gettysburg College professors.  I asked one of them whether faculty could bring their dogs to work.  She replied “The college’s Affirmative Action lawyer, before she left, made up a lot of new rules.  One of them was that junior and senior faculty could not sleep together.  Another was to ban dogs in the buildings.”


This is a good measure of how desperate PhDs are for jobs as college professors.  The college pays lower salaries, to people of the same age, as the public high school down the street.  The high school teachers were able to go to work at age 22 without suffering through a long period of starvation wages as graduate assistants.  The high school teachers are union members who ever have to worry about losing their job, compared to the college professors who live for 7 years in fear of being tossed out as a middle-aged has-been (“denied tenure” is the polite term for this event).  And now these poor souls are expected to get through their day without a dog at their side and without the possibility of an interlude with a more senior professor.


[Note to parents:  if you want to know why tuition prices have risen so fast, consider that a very small liberal arts school was paying a full-time lawyer to work on affirmative action; Walmart has a “Chief Diversity Officer” but they had $billions in revenue over which to spread the cost.]
